Core Tip

Core Tip: This critique highlights key methodological limitations in Xu et al’s predictive model for cognitive impairment in elderly hypertensive patients. Chief concerns include the small validation sample, potential reverse causality due to the cross-sectional design, insufficient discussion of alkaline phosphatase as a biomarker, omission of key cognitive risk factors, and possible overfitting. We recommend external validation, longitudinal analysis, incorporation of psychosocial and genetic variables, and rigorous calibration to improve reliability and clinical applicability.
